3.4.1 Precautions for non-linear and
sensitive loads
The most common non-linear loads are thyristor/
rectifier-controlled loads, such as convertors
supplying voltage to variable speed motors,
uninterruptable power supplies and Telecom
supplies. Gas-discharge lighting arranged in single-
phase circuits generate high 3rd harmonics and risk
for excessive neutral current.
Loads most sensitive to voltage distortion include
incandescent lamps, discharge lamps, computers, X-
ray equipment, audio amplifiers and elevators.
Consult Atlas Copco for measures against the adverse
influence of non-linear loads.
Non-linear loads draw currents with
high contents in harmonics, causing
distortion in the wave form of the
voltage generated by the alternator.
